Your argument re: Caedus is that Caedus doesn't bother to mention his injuries as a hindering factor at the start of the fight, so they must not have been a problem and we should try to come up with reasons as to why. Well Starkiller doesn't mention his fatigue as a hindering factor at all, so by your logic, we should come up with reasons as to why (which is easy - time to recover + intense motivation / adrenaline). Starkiller mentions before he knew he was going to fight Vader that he is exhausted, just like how Caedus mentions before the fight begins that he is injured, but then there's an ambiguous time lapse.
It's very simple. The wounds do strengthen him. This should be assumed the default paradigm for Caedus until stated otherwise. That Caedus claimed those exact wounds fuel his power and then presents them as a negative in an exceptional situation, does not mean this ability has disappeared wholesale. It just means that this power is impeded in that moment. You only need a novice level of research on how Jedi and Sith wield their powers to come to that conclusion. If we look at the fight itself :
OK, you still haven't explained:
1. That he gets blindsided by the blaster bolt, so his concentration is slipping before that injury.
2. Why he doesn't mention the blaster injury as a greater problem than his injuries from Luke.
3. Why we should even care, since he is dominating the fight before the blaster bolt anyway.
The most you can conclude is that his injuries strengthen him in very specific ways, but that this strength is extremely flimsy - it can give him a +15 buff passively but even the slightest distraction or aggravation and it turns into a -30. That may be better than other characters for which it's consistently a -15, but then we circle back to point #3, which is why whether he wasn't hindered at the start of the fight even matters. I guess you've demonstrated that Caedus can't ragdoll Katarn? Are you trying to note that he viewed Katarn as a "threat"? Because someone having a 5% chance of killing you is still a significant "threat", especially given that his injuries can be aggravated into hinderances at the slightest provocation.
As for Katarn and his standing in the history of the Jedi order. That all the Jedi before the prequels are in the trash bin because of quotes found on the back of chocolate bar wrappings, and the a rare few PT top dogs are truly exceptional to be above everyone that had a name and a lightsaber,
Well:
1. Those "chocolate bar wrappings" still hold weight when there are like 15 of them.
2. As I'm sure you know, there are multiple sources that are clearly not the back of "chocolate bar wrappings", like the RotS novelization.
The logic is pretty simple: Sidious is the most powerful Sith, and there are three Jedi who can to varying levels compete with Sidious (Yoda, Mace, and, whether you agree, Anakin), so they get dragged far above the ancient Jedi who were always vastly weaker than the top Ancient Sith.
tells me that Katarn is more likey to dwell amongst everyone who existed in the 20,000 years before, as someone without the required accolades. Even though he technically skirts the quotes by existing after their chronological expiration date.
You're assuming that whatever factor caused the PT to have so many powerhouses went away with the Jedi Order. For whatever IU reason (poor balance of the Force maybe? Mortis?), the few decades surrounding the movies have spawned more potent Force users than the entire previous history of the Old Republic.
